Final answer:
No, in compound meters, a dotted note does not equal a beat.
Step-by-step explanation:
No, in compound meters, a dotted note does not necessarily equal a beat. The duration of a dotted note is extended by half its original value. For example, if a quarter note is dotted, it would last for a beat and a half. However, the actual number of beats in a measure and the value of a beat can vary in compound meters.
Compound meters have beats that are subdivided into three equal parts. One common compound meter is 6/8, where there are two beats per measure, and each beat is divided into three eighth notes. In this case, a dotted quarter note would last for one and a half beats, not one beat.
Therefore, the statement 'a dotted note equals a beat' is false in compound meters.
